Question

Q.which of the following do not represent electric power ?
(A) P=VI. (B)P=V"Q/T
(C)P=I^2R. (C) P=I^2RT​

Answer 1

Explanation:

Answer: (2) IR2

In physics, the rate of electrical energy transfer by an electrical circuit per unit time is determined by electric power. It is denoted by P measured using the SI unit one joule per second or watt.

The formula for electric power

P = VI……………………..(1)

Where

P = Electric power

V = Potential difference in the circuit

I = Electric current.
